Ann: 41 Diamonds Recovered From Lulo Kimberlite L164 Bulk Sample, page-4

Not sure if this is wet or dry but an interesting comparison. Note Letseng quoted in the ann is at the bottom of the list.

SO these results are per hundred ton so divid by 100 = 0.017 CTP - that would put in WAY off the bottom of this chart. Then have to divide by LOM's pathetic % - was it 40% ? sorry can't remeber

At least it is a start I guess.
